F.Belitknownftha'twe GEORGE F. CoLBnrJr and'lYrnLrAM'HrCoLnnr, citizens of the JUnited Stateswand"residents of Pittsburgh,

in the county lof.Allegheny and State of Pennsylvania-i, have invented a new and useful Improvement in AMirror-Supjiorts; and we do hereby` declare the following to be a full, clear. and exact description thereof.

.'Our inventionvrela'tes to mirror-supports, and while theinvention is not intended to be limited to any particular purpose. it is especially adapted for use in connection with automobile mirrors which are set up in convenient position at the front of the car so thatthe drlvercan'obtaln a View o'f the l roadway in the rear to guardv against accidents fromvehicles approaching in that directionj I.. 20-

The object'of our invention is to provide a s upport in which the mirror is rigidly and firmly held so as to prevent'the vibration of the ,mii'ror, which is liable to result iu th-ecracking or breaking of same, while at the same time the pressure on the mirror is not so great as to tendl to crack or break the same by-undue pressure.

`To these ends our lnventioncomprises the glass from flying in case the mirror shouldv be broken in a collision or other accident, the mirror is preferably backed with leather or like material.

The holder is made up of parts:

The clamping plates 4 are formed of metal of proper gage` said clamping plates extending longitudinally along the back of the mirror. and said Vplates have lat their inner ends the lugs 5 with openings therein through which the adjusting screw-bolt 6 the following passes, provided with the nut 7. It will be apparent that by loosening or tightening the bolt 6 the clamping plates may be adjustedto tighten or loosen their hold on the l Specie'aton ofLetters Patent.

mirror. At the outer ends of the clamping plates l are the outwardly projecting clips 8 which engage thebevelcd ends of the inirror. The mirror slipped edgewise into position to engage the clips 8, whereupon, by tightening up the bolt the mirror securely and firmly clamped in position.

At the outer ends of the clamping plates el are the inwardly extending lugs l() with openings formed therein. bar 11 has the outwardly projecting end portions 1Q which are adapted to register with the lugs l() on the. clamping plates l. said outwardly extending portions l2 haying openings registering withthe openings 1n said lugs. Screw-bolts 13 pass through said openings Securing said bar to said clamping plates. forming a pivotal connection so that the mirror may be tilted in a vertical plane to such aposition as indicated by dotted lines. Fig. 3. Tira-shers l-l, formed of fiber or other suitable material.. are interposed between the lugs 10 of the clamping plates 4 and the outwardly projecting portions 12 of the bar 11, said washers creating the necessary fric-- tion to hold the mirror in adjusted position. and at the same time allowing for the adjustinent of the mirror without undue pressure having to be applied. The fiber washers also tend to prevent vibration and rattling when the car is in motion.

An angle plate 1l is riveted or otherwise secured to the bar 1l. said angle having the opening 11b through which the screw-bolt 6 passes after passing through the unit i'. This eliminates `Vibration between the mirror and the frame. and furnishes another friction point to hold the mirror in adjusted position.

`Secured to the bar 11 is the extension 15 with the circular platev 16. A bracket 17 has a like circular portion 18 coinciding with the Circular portion 16. said parts having registering openings through which the pivoting bolt 19 passes. A fibrous or .like washer 2() is interposed between the plates 16 and 18. and provision is thus made for the turning of the plate 16 on the plate 18 for swinging the mirror at an'angle. as indicated in Fig. 2, the fiber washer Q0 creating sutlicient friction to hold the mirror in such adjusted position.

The bracket 17 has the openings 21 to receive screws or -like fastening devices for securing the mirror-support in osition atany desired place vat the front ofp the car'.

`vthefnecessary friction and resistance.

By our invention we provide a' very simple form of mirror-supportin which-the mirror is firmly and securely held in place, and yet not so rigidly as to endanger the cracking or breaklng of the mirror due to too much pressure. The mirror is engaged at the ends by the clips and is supported and reinforced for its entire length 1n the back by its clamping plates which gives additional strength. f

The mirror is readily adjustable either in a horizontal or Vertical planefand when once adjusted will remain 1n such adjusted position without tightening up any screws or like devices, the fibrous washers creating vWhat we claim is: y

1. The combination with a mirror, of

yclamping plates extending along the back of said `mirror longitudinally thereof, said clamping plates having outwardly projecting clips lengaging the ends of the irror, lugs on said clamping plates, a. justing bolts engaging said lugs, inwardly 'extending lugs at the outer ends of Said clamping plates, a bar having outwardly extending portions ivotally connected t0 said lugs, a rearward y extending horizontalportion on said bar, and a bracket having a horizontal portion pivotally connected -to said horizontal extension.

2. The combination with the mirror, of clamping plates extending longitudinally in the rear of said mirror, said clamping plates having outwardly extending clips en- `pi'votally, connected to said lugs, a

ing extension pivotall connected to saidv -rst extension, and a\ brous washer interposed between said extensions.

3. The combination", with the mirror, of clamping plates extending longitudinally lin the rear of said mirror, said clamping plates having outwardly extending cli s engaging the ends of thejnirror, inwarc y extending luofs at the `inner ends of said clamping plates, an adjusting screw en ging said lugs, a longitudinally extent ing bar having outwardly extending portions rojection on said bar enga ed by said adjrilsting screw, a bracket, an ivotal connections between said bar and said bracket, whereby the horizontal movementy of said mirror may be effected. i

In testimony whereof. we, the said GEORGE F. CoLm-:R'r and WILLIAM H. CoL- nER'r, have hereunto set our hands.
